Over the last ten years, Japan has witnessed a two-fold increase in the number of surgical abortions among the teenage population. The increase in teenage sexual activity indicated by this trend has been a source of much concern and study. The accelerated social change going on in Japan over the last century has produced a series of contrasting generations, each differing in social attitudes fr...

Two sensitive methods are described for detection of DNA dependent DNA polymerase activities in polyacrylamide gels after their fractionation by micro-disc electrophoresis. One technique is based on the increase in fluorescence of the ethidium bromide complex with template polydeoxyribonucleotides brought about by the action of the polymerases. The sensitivity of the previously described techni...

This paper shows why, in a world with differing priors, rational agents tend to attribute their own success more to skill and their failure more to bad luck than an outsider. It further shows why each agent in a group might think he or she is the best, why an agent might overestimate the control he has over the outcome, and why two agents’ estimated contributions often add up to more than 100%....

Semantic cognition is underpinned by regions involved in representing conceptual knowledge and executive control areas that provide regulation of this information according to current task requirements. Using distortion-corrected fMRI, we investigated the contributions of these two systems to abstract and concrete word comprehension. We contrasted semantic decisions made either with coherent co...

The hippocampal CA3-CA1 synapse is an excellent experimental model for studying the interactions between short- and long-term plastic changes taking place following high-frequency stimulation (HFS) of Schaffer collaterals and during the acquisition and extinction of a classical eyeblink conditioning in behaving mice. Input/output curves and a full-range paired-pulse study enabled determining th...

Benznidazole is the main drug used to treat Trypanosoma cruzi infections. However, frequent instances of treatment failure have been reported. To better understand potential resistance mechanisms, we analysed three clones isolated from a single parasite population that had undergone benznidazole-selection. These clones exhibited differing levels of benznidazole-resistance (varying between 9 and...
